In a ,copending application of Eber J Hubbard, Serial N 0." 406,772,filed November 3rd,; 1929, there is disclosed a reel whose laminated enddiscsor heads are provided withjai sheet metal reinforcing rim or tireintimately clinched thereto, and with sheet 15- metal bushings clampingthe lamination together at-theaxes of the heads. An iinportant object ofour invention is to provide simple and efiicient apparatus for quicklyand economically applying the rim or tire 2o with securing clamping andclinching engagement to the periphery of the head and during the sameoperation applying a sheet metal bushing in an axial bearing passage'thi 'oughthe head/co rigidly and securingly clamp the head.lamin'ations together at the head axis. ,The' various features ofourinvention are embodied in the'structure disclosed on theaccompanyingdrawings, in which Figure 1 is side elevation showing therelatively movable parts of a press and the ,re'enforc'enient applyingapparatus mounted thereon; 7

Figure 4 is a similar sectional view showing the parts after thepressure and applyingoperation Figure ,5 is an enlarged cross-sectionalview of the reel head and reinforcing rim in embryo form; and

Fig. 6' is a similar sectional view showing the rim fully applied.

On the drawings, 10 represents the base or b'ed and llthe reciprocalhead of a press, the bedand head having opposed cylindrical depressionsor pockets 1 2 and 13 respectively.

placed in the apparatus ready for theapply Surrmin'dingthe bed pockets12 is anannular boss 14 forming a seat for the lower annular die 15, thedie abutting against the shoulder 16 on the boss and havin its innerface flush with the inner face of the pocket 12. 'The movable head ofthepress has the annular recess 17 surrounding. the pocket 13 in whichrecess is seated the annular upper die 18 with its inner face flush withthe cylindrical side of the pocket 13.

Reciprocal within the die 15 a circular supporting discor plate 19 whosediameter is substantially equal to the inner diameter of the die,andinterposed between this plate and the bottom of the pocket 12 are anumber of compression springs 20 which tend to hold the plate in itsouter position indicated in Figure 3. Stop studs 21 extend down,

wardly from the plate and through Ushaped brackets 22 secured to thebottom of the pocket, the heads 23 on the studs, by their engagementwith the bracket ends, limiting the outward movement of the plate.

The "late 19 has the axial cylindrical passage- 2 for receiving thecylindrical die stud 25 piojectihg upwardly from the press bed 10' inthe pocket 1.2, this die stud having the I outer reduced end or neck 26for a purpose to be hereinafter more fully explained.

Reciprocal within the upper die 18 is a circulardisc or plate 27 whosediameter is substantially the same as the inner diameter t v of the dieand between which and the bottom Figure 2 is a plan viewof-the'apparsttus;

of the pocket 13 are interposed a number of compression'springs 28 whichtend to hold the plate in its outer position as shown in Figure-3. Thestuds 29 extending from the plate through the brzicketsBO secured to thepress head 11 have the heads 31 for engaging against theouter ends ofthe brackets to limit the outward movement of the plate 27.

The reel head, for the assembly and reenforceine'nt of which ourimproved ap paratus has been designed, comprises two circular discs 32and 83 which may be of non-metallic material such as wood. Thereinforcing rim or tire T is primarily of the cross-section shown inFigure 5. This initialiorm is obtained by rolling a length of plain bandof sheet metal to circular radially inwardly from the groove 35, and theouter edge section E of each disc between the groove and the recess isrounded to be of substantially semi-cylindrical crosssection. Aroundthese semi-cylindrical edge sections the sides A of the embryo tirestructure are to be intimately deflected with their ends within therecesses 36 as indicated in Figure 6, these sections being then securelyclamped by the clinching thereto of the tire structure sides.

The annular dies and 18 have the die or forming .grooves '37corresponding in shape with the peripheral edges of the discs aroundwhich the sides A of the tire are to be clamped and clinched. Referringto Figure 3,the press head 11 is normally raised away from the bed 10and the supportingplates 19 and 27 are'in their outer p0sitions.- When areel head is to be assembled and reinforced, two discs are applied fromopposite sides into an embryotire structure to receive the ridge 35, andthe assembled discs with the tire structure thereon are then laid on topof the lower plate 19. e

In order to accurately align the discs and the embryo tire with theannular dies and to hold the tire against distortion while the the sidesare being deflected sand clinched around the disc peripheries, analigning and clamping frame F is provided. This frame is annular andconcentric with the annular dies and is preferably composed of the twosemi-circular sections 38 and 39 hinged together by a pin 40 at one endand having their other ends detachably locked together by a suitablelatch asfor example a hook 41 pivoted to one of the members and a pin 42on the other member, the hook being readily operableby its handle orgrip 43. The member 38 of the aligning and'clamping frame is; securedagainst radial displacement} by means of pins 44 extending upwardly fromthe pressbedlO and these pins also serve to center and align the presshead 11 relative to the bed when the head is forced down.

'The frame F is, however, free for axial the movement, such movementbeing guided by pins 44. v

Each of the frame members 38 and 39 has a number of pockets 44 providedwith re movable covers 45. A foot 46 extends downwardlythrough anopening 47 in the base Each disc has also an annular recess 36 in itsouter side a short d1stance' of each pocket 44 and within the-pocket hasan abutment head 48 for a compression spring 49 which abuts at its upperend against the cover 45. The feet 46 rest on the press bed 10 andnormally the springs are extended to hold the frame in verticalalignment with the reel head forming parts placed on the'plate 19, theframe members having the semicircular dies or engaging inserts- 50 and51 of such cross-section that at their inner ends they will fit into theannular belt groove 34 formed in the outer side of theembryo tire by theridge 35 therein. Before the head discs with the embryo tire thereon areapplied to the plate f 19, the frame member 39 is swung outwardly tomake way therefor and then the member 39 is swung back and interlockedwith the member 38 by the hook 41, a handle 43 forming a convenientmeans for swinging the member 39. The die andabutment inserts 50 and 51willthen engage in thetire groove and will hold the discs and tire inaccurate alignment 011 the press readyzfor the clamping and clinchingoperation. The press is now started and as the press head 11 travelsdownwardly itsplate 27 will first engage with the upperreel head discwhere-' upon the springs 20 and28v are put under compression so that thereel head'discs are securely but resiliently clampedtogether between theplates 19 and 27. During such.

clamping'the plates move downwardly with the clamped discs and the frameF will move downwardly therewith, and pins 44 on which the frame member38 is slidable, serving to accurately guide the frame F in itsdownwardly movement, and such move ment is resisted by the compressionof the springs 49. Eventually, the annular dies 15 and 18 reach theprojecting sides A of the embryo tire structure and these sides arecurled, clamped and clinched around the semi-cylindrical peripheralsections of the reel head discs, the frame F rigidly holding the centralportion of the tire during such deflection and clamping of the sidesections of the tire and during such opera tion the spring'pressedplates 19 and 27 hold the reel head discs securely against each other. i

The reel heads usually have axial openings for. receiving a supportingshaft for the reel during winding or unwinding thereof. To reinforcevsuch bearing openings sheet metal bushings are preferably provided andour improved apparatus may be readily adapted to apply such bushingssimultaneously with the clinching of the tire structure to theheaddiscs.

the press a sheet metal bushing 52 is inserted in the registeringopeningsv 53 provided therefor in the discs. Such bushings may readilybe formed by rolling from a sheet Either be fore or after the head discsare placed in i is 'p ovi metal blank sirdprereratty the edges of thebushi' g have serrations or teeth 543'. For clamping these bushings tothe heart discs the die stud 25, already reierr'e'd to, ed on' the presshead A corn p; in die'stud 5o is' providedon the press hear sashes thereduced end or neck 56 like the neck- 26 of the stud 25. The upper plate27 has the opening 57 for,receiving V thestu'd and as the press head ismoved downwardly the plate openings 24% and 57 receive the studs and'55respectively and: the stud necks enter the opposite ends of the bushing52, Then as the serrate'dends of the bushings areengag'ed by theshoulders 58and 59 of the respective die studs, they "are deflectedradially outwardly-and then downwardly against the outer face of thediscs32 with the teeth or serrations impressedinto the discs so that thebushing will be securely locked against ro tation in thediscs: When thepress head 11, is now withdrawn, the frame member- 39 is swung open andthe finished and reinfo'rcedreel head is removed'from the press;

7 The apparatus pzirtsare rest red to their normal -position by their.springs ready for receiving another charge of reel headform- ,ingparts.

We thus produce a simple and efficient apparatus by insansbf which areinforcing sheet metal tire and bearing bushing may bequickly,accurately and economically ap plied to non-metallic discs, to form areinforced reel head.
